Socrates Quotable Quote 

"No man has the right to be an amateur in the matter of physical training. It is a shame for a man to grow old without seeing the beauty and strength of which his body is capable"

Cows Eye Dissection

 Eye Dissection

Aim: To dissect a cow's eye and look at the different parts of the eye.

5 Types of Leadership

 Leadership is taking charge and being a role model for others. Its also helping others and knowing what to do and when to do it. 

Earlier in the week we did a quiz and it showed what type of leader you are. I kind of agree with what I got and agree that you can never be too experienced.

Refraction through Lenses

Refraction through Lenses

Aim: To investigate how different types of lenses refract light.

Equipment: Triple-slit ray slide, power supply, a concave lens and a convex lens

Method:

1. Set up a ray box, triple slit ray slide and power supply 

2. Place the convex lens in the space below. Place the ray box at the top of the page and shine the three rays of light at the lens. Make sure the central light ray hits the lens at 90 degrees as indicated in the diagram.

3. Carefully trace the direction of the incoming and refracted rays.

4. Repeat using the concave lens.

Conclusion:  The following sentences describe the way light refracts through the two different lenses. Read the sentences and identify which lens relate to each sentence.

When light passes through this type of lens, the rays all move away (diverge) from each other. One use of these lenses is in security peepholes in a door so that a person inside a room can see who is at the door without having to open it.

The lens described in the paragraph above is a convex lens

 

Reflection and Refraction

Reflection and Refraction

Reflection - The bouncing back of a wave when it hits a surface through which it cannot pass.

Refraction - The bending of a wave as it passes at an angle from one medium to another

Incident ray - incoming ray

Reflected ray - the light that has bent as it enters a new medium

Normal Line - imaginary line drawn perpendicular to the surface of a mirror or any surface

Angle - The amount of bending that a light ray experiences

Law of Reflection

The law of reflection states that when a ray of light reflects off a surface, the angle of incidence is equal to the angle of reflection.

Speed of Light

Speed of Light

Aim: To investigate how light behaves when it hits a plane (flat mirror)

Equipment: Light box, Transformer, mirror and paper protractor / plastic protractor.

Method: 

1. Collect a ray box, power supply, and single slit ray slide from your teacher, and set them up to produce a single beam of light.

2. Place a plane mirror on the diagram of the protractor as described.

3. Vary the angle of incidence and record the angle of reflection in the results table.

Results: 

Angle of Incidence	Angle of Reflection
0°	0°
10°	10°
20°	20°
30°	30°
40°	40°
50°	50°
60°	60°
70°	70°
80°	80°

Achievement DLO

 Achievement DLO

Our value focus for this term in achievement.

Achievement means completing a goal or earning something. 

Achievement in school is trying you best and achieving all you can.

Achievement outside of school is completing goals you have in life and trying the best you can.

Achievement overall is having goals to complete and completing those goals.

An achiever is someone who achieves great things.

Holidays DLO

Holidays DLO

Here is a post on what I did during these past school holidays.

During these holidays I spent most of my days sleeping, playing xbox and hanging out with friends.

On the second week of the holidays two of my friends and I went to Wycola to try out the new sushi shop, we were in luck as since it was opening on that day they were giving away 100 packs of free sushi. Afterwords we went and hung out at the park.

During the holidays I felt great since I had so much free time to do whatever I wanted.

Thank you for reading and I hope you enjoyed your holidays!
